Alfetta Euro manifold

[fiatosca]

I purchased a cast iron two piece Euro exhaust manifold for my Alfetta Sedan.
Here's the problem; it doesn't fit. The motor is on a stand and I cannot get the #1 - #4 portion to line up with the head studs. The smaller #2 - #3 piece slides right on. I at first thought that perhaps I had bent the studs during engine removal but the original manifold slides on just fine. Suggestions?

Can you post a picture of the manifolds? Maybe they are not really from a Nord Engine.
